Reliance Infrastructure, which is the concessionaire for the Airport Metro Express Line of the Delhi metro in the national capital, has accused the Delhi Metro Rail Corporation (DMRC) of forcing it to use faulty chips in the underground section.

The company has complained to the Union Urban Development Ministry that it was under pressure from the DMRC to use ssloh fastening clips for the underground section of the airport metro line in Delhi. The authorities had to close down the Airport Metro Line because of repairs after the company found serious faults in civil works and the clips that were used in the underground stretches of the line.

After an inspection of the line, it was found that about four per cent of the ssloh fastening clips were damaged. The company said that DMRC forced the concessionaire to keep the trains operational even as it had identified faults in the line.

Reliance Infrastructure said DMRC did not agree to a suggestion put forward by the company and put forward a list of companies to source clips and the list included Vossloh. The DMRC game Reliance Infrastructure a list of three companies, out of which two were Vossloh and a company called Patil Vossloh, it has been indicated.

The DMRC has responded by saying that it did not make any suggestion of that sort and no particular company was suggested to Reliance Infrastructure.
